This really is a shame.
Samsung is either unable, or unwilling to fix the issues that keep coming up time after time. There's really no excuse for it. They
know image quality is terrible under Game Mode. They
know of the horrible flashlighting effects. Do they give a damn to fix them? No, of course not.
It's like they're playing down the level of their competition. They don't want to put forth the effort and money to address recurring issues unless they're forced to. They'd rather put more money into a new snazzy looking design for the stand.

And there's nothing we can do about it. As long as the average joe is willing to blissfully fork over $2,800.00 Samsung won't be compelled to do anything.
I'd be willing to bet their next 55" LED has the exact same issues, while costing more. Samsung FTL.
